抄録

Self-assemble monolayers of binary molecules were studied by scanning tunneling microscopy. Di-indenoperylene (DIP) and fluorinated copper-phthalocyanine (F<Sub>16</Sub>CuPc), which are p-type and n-type organic semiconductors respectively, were co-deposited in ultra-high vacuum on Au(111) and Cu(111) surface. STM observation exhibited the molecules formed well-ordered intermixed monolayer on the metal surfaces. Theoretical calculation revealed C-F…H bonding between neighboring F<Sub>16</Sub>CuPc and DIP was a dominant force for the ordered phase formation. Orientation, alignment and domain formation were determined by balancing molecule-substrate interaction as well as such intermolecular interaction, and as a consequence showed dependency on the metal substrates and ratios of the molecules. Thus, the ordered phases were formed only at certain molecular ratios and were named as "molecular alloys" after those of inorganic materials.
